This is a possibility, it's a bug in that case, I have a vague memory of
something similar being reported some time ago.
As for running MusE suid, this is in itself not a problem unless your machine
is compromised, in which case you someone use it to lock up the machine
(which is equally true for rtcap:ed muse). The prospect that someone has
bothered to find a security hole in MusE to gain control of a machine through
it's suid usage seems a tad unlikely.
